Seeing Link approach with such a humble attitude, eager to learn, Ryze naturally didn't turn him away.
He patted Link on the shoulder and chuckled, "If it were about some other talent, I might not be able to help you much. But Soul Oath? That's a talent I've spent most of my life researching. So, while I can't guarantee I'll help you maximize every last drop of potential, getting you to eighty or ninety percent efficiency? That's no problem at all."
"And besides…" Ryze gave Link a half-smiling, half-sighing glance. "Though I don't really want to admit it, I have to say—Soul Oath, when paired with your Death Replication, is virtually without drawbacks. That's why the focus of your oath shouldn't be the content of the vow itself. What you really need to consider… is how to use your own abilities to amplify the oath to its highest potential."
"In other words, I can give you a nine. But that final one—only you can earn it."
